Fix carbs event time

[Andries-Smit]

The carb dialog allows a user to enter an offset in minutes, and an event time through the date/time picker. This gave an inconsistent UI
Where it was possible to change both.

The expected behaviour;

1. When the Offset time is changed, the Event time is updated.
2. When the Event time date is changed the Offset time is updated.
3. When the Event time time is changed the Offset time is updated.
4. The + and - 12 hours limit set through the Offset time will be enforced on the Event time too, working together with PR Fix/number picker set limit #1233

Note: no side effects are expected on the other dialogs that are using the DialogFragmentWithDate in combination with Number/Minute picker.

• Additional I made the insulin dialog with the "Do not bolus, record only" option to use the minutes picker too
